HARRY L. HAMMOND, OF INDIANAPOLIS, INDIANA.

WINDOW-FASTENER.

Specification of Letters Patent.

Patented Dee. 24, 1907'.

Application filed August 13, 1907. Serial No. 388,299.

T o all whom it may concern.' f

Be it known that I, HARRY L. HAMMOND, a citizen ofthe United States,residing at i Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements inIWindow-Fasteners, of which the following is a specification.

rlhis invention relates to a device for fastening windows; and theobject of the invention is to provide a window fastening device whichwill be extremely simple in construction, inexpensive to manufacture,and neat in appearance.

I accomplish the objects of my invention by a window fastening deviceillustrated in the accompanying drawings, in which- Figure I is afragmentary detail view in perspective of a window-casing, showing myimproved fastening device in operating position. Fig. 2 is a centralvertical sectional view through a portion of the window-sash and frame.Fig. 3 is a transverse sectional view of one side of the windowfcasing,on an enlarged scale, showing by means of the full lines the sashfastener in operating position, and by means of the dotted lines itsopen position.

In the drawings, 1 constitutes an ordinary window-frame or casing, 2 theupper sash, and 3 the lower sash. The frame is provided with theparting-strips, etc., all of which is old and well known.

My fastening device consists of a narrow piece of material 5, eitherwood orrmetal, which is secured by means of the hinges 6 to the innerguide strip 7 secured to the window casing l. The strips 5 may be placedon each side of the casing 1 so that greater security is afforded; Thestrips 5 are of a length to extend from the upper edge of the lowersash, when closed, to the upper end of the window-frame l. By means ofthe hinge mounting of the strips 5 they may be swung in over the upperedge of the lower sash when the latter occupies an extreme lowerposition, and when the strips 5 are turned outward, as shown in thedotted p0- sition in Fig. 3, the lower sash may be moved upward.

To prevent the upper sash 2 from being lowered I provide said sash withlittle blocks or circular disks 10 which are secured to the innersurface of the sash and near its upper end. The blocks or disks l0 whenin position form projecting shoulders which are engaged by the shouldersl1 formedA on the strips 5 by providing the upper ends of the stripswith recesses, which permit said strips to be closed. The blocks lO arepreferably formed round so that sharp corners are eliminated. It will benoted that when the strips 5 are closed the corners ll will move inunder the loweredge of the disks l0 and thus prevent the upper sash frombeing lowered. It

will be noted that the strips 5 when in closed position are hardlynoticeable and do not look unsightly or mar the window-frames. To makethe fasteners less conspicuous they are generally made to harmonize withthe nish of the room in which they are used.

Having thus fully described my said invention, what I desire to secureby Letters Iatent, isf In a window fastening device, the combinationwith the casing and sash, of a movable strip hingedly secured to thecasing and susceptible of being moved over the upper edge of the lowersash and extending to and abutting the upper end of the window-casing,said strip being provided with a notch, and means on the upper sashadapted to engage the notch on the strip.

In witness whereof, I, have hereunto set my hand and seal atIndianapolis, Indiana, this 6th day of Aug., A. D one thousand ninehundred and seven.
